      Question 1

      BioDigital’s Human 3D Anatomy app lets students, educators, and healthcare practitioners manipulate interactive images of different systems and structures. In the image of the eye, which structure is outer layer of the eye, where light first makes contact?

      Question 2

      The capacity to judge distances by detecting retinal disparity and other perceptual cues depends on the eye’s ability to focus on specific objects. This focusing ability, or visual accommodation, requires that which portion of the eye be able to change its curvature?

      Question 3

      In order for your brain to process visual images, those images must first pass into the brain from the retina. Which structure transmits this information from the retina to the brain?

      Question 4

      Sam has red-green colorblindness, so he has trouble detecting shades of red and green. This condition is a result of a deficiency in which part of his eye, responsible for detecting color?

      Question 5

      As can be seen in the 3D Anatomy images, the eye is surrounded by a network of muscles and ligaments that produce a variety of movements. Researchers organize the many different eye movements into three categories. Which type of eye movement describes the jumps that take your gaze from one point to another?
